Gamsol is a refined OMS (Odorless Mineral Spirit) for a high level of performance in brush clean up also suitable for general use in oil painting.
How does Gamsol achieve a superior level of performance and safety? Most solvents available to artists come from the industrial paint industry where solvent power and cheapness is prized. Gamsol is special. It is made for products and processes that come into more intimate contact with the body such as cosmetics, hand cleaners, and cleaning food service equipment.
Gamsol is a petroleum distillate but all the aromatic solvents have been refined out of it. Less than .005% remains. Aromatic solvents are the most harmful types of petroleum solvents. The Gamsol SDS shows that it has an Exposure Limit Value higher than most solvents available to artists. In addition, Gamsol’s flash point allows it to ship via air cargo as a non-hazardous material.
All of these factors have lead to Gamsol being used widely in oil painting classrooms; in those classes, there are no solvent odors, only the wonderful smell of oil colors.
